Patent GB-854601-A (GB)
Abstract: 854,601. Parachutes. IRVING AIR CHUTE OF GREAT BRITAIN Ltd. March 25, 1959 [April 3, 1958], No. 10889/58. Class 4. In parachute packs of the type provided with readily-releasable attachments to the wearer's harness to enable the pack to be removed under normal conditions of flight, the attachments are made by what are referred to primary and secondary connections so arranged that upon a jump being made, the attachments are not prematurely freed so that the pack rises above the parachutist to the limit of the lift webs whereby the parachute manual release handle is beyond reach. The body harness 1, secured in conventional manner by apertured lugs 2 engaged within a quick-release box (not shown) carries conventional lift webs 3 each terminating in a snap hook 4 which is releasably housed within a spring clip 5 attached to a platform 6 fast with harness 1. A further hook 7, to be described, is mounted on each platform and each pair of hooks 4, 7 is surrounded by a protective shield 8. The parachute pack 9 has attached to its rear wall two pairs of D rings 10, 16 which project both inside and outside of the pack, the rings 10, referred to as primary connectors being rigidly attached to the pack and adapted to snap into hooks 4. The rings 16, which are prevented by plates 17 from entering the pack but which are capable of being withdrawn outwardly, are referred to as the secondary connectors and these engage hooks 7. Each ring 10 is connected by straps 11 to a ring 12 attached to parachute rigging lines 13 and each ring 16 is also attached to ring 12 by a strap 14, shorter than strap 11, which terminates in a tongue 15 which prevents the outward movement of hook 16. In use the pack is attached to the harness by pressing it against the body so that rings 10, 16 spring into hooks 4, 7 and upon a jump being made the parachute is released from the pack so that the drag on lines 13 initially tensions straps 14 to withdraw tongues 15, thereby releasing rings 16 from the pack and subsequently, through straps 11 and rings 10, snaps hooks 4 out of clips 5 in order that the parachutist may be supported from lines 13 by straps 11 and 3. A single secondary connecting device may be positioned centrally between two primary connectors.

Title: Low voltage track lighting system
Inventor: SILLETT MARK JOHNATHAN
IPC: H01R25/14
Filed: 1986-01-28
Abstract: A low voltage track lighting system includes a track assembly comprising an elongate insulating support 2, and a pair of circular conductors 4 housed in open channels, the conductors 4 being resiliently held in each channel by a rib 2a. An adaptor fitting for the track assembly comprises an H- shaped clip 14 of resilient material with a pair of contacts 18 and 16 lining opposing inner faces of the upper limbs 14a and 14b of the clip 14. Each contact has an inwardly directed contact portion for engaging a respective conductive track 4. By squeezing the two lower limbs 14g and 14h of the clip together the two upper limbs 14a and 14b can be moved apart to release the contacts 16 and 18 from the tracks 4. Thus operation of the clip member 14 enables the light fitting to be readily removed from or fitted to any desired location along the track assembly. A lamp 10 clips into the lower end of a stem 8 of the adaptor. <IMAGE>
